Ciao Cesar, notice that a geotiff cannot be larger than 4gb. It is a format limitation not a geotools limitation. We have a student that is trying to extend imageio tiff plugin to support bigtiff as well, but for the moment no work should have been performed on writing bigtiff. If you are interested I can try to check with him next week.
